f'rtop' 33 is provided for the base and rests nponthe upper edges of the ivalls andl 8, andthe rear edge of the top abuis the portionE of the back 4 Which extends above the tops ai the remaining vWalls. The top 33 is fastened. in position in any desired manner and is provided with store holes or openings, preferably three, each having a lid 3l. One of these stove holes is provided through the topf between the dainper's '20-2l androne is provided on each side of the pair of dani pers Jas shown. Thus if the dainpers are adjusted to the positions shown in Fig'. Q, the v will act es baffle' plates. or detlectors to equally distribute the heated air to all oli the store holes.

It, however.y the dainpers are adjusted so that'theiT will rest lint against the lower. face of the top and with their free edges suhstantiallaY in Contact, they `will pre- 4 l passage orspace Q5 which. is provided- I' to furnish 4air to the burner '26, which latter isarr'anged adpicent the opening 7 in the .incomes vent the heated air from being discharged to,

the central store hole but will deflect such heated air to the other holes. Thus itl will be seen that the danipers may be manipulated at 'will to control the directionoit flow of the heated air so that the ainount conducted to anyv one or inore oit the stove holes may he Varied.

The portion of the top overthe chainbersI in the rear of the partition l2 is provided with openings 3G-3T forming p assz'iges for the heated air haring` counnuni.- cation with the respect-ive chambers. The bach il as before stated7 extends for any desired distance ahore the top 33 and forms the back ivall of an oven which is of a length equal to the length ot the base, and may he of an;1 desired size. rl`he bottoni thereoiE is prelieinbljv7 of a Width substantially equal to the ividth ofthe top The sides 3") ol the oren are foi-ined by uprigrhls iisi ein the base ol the apparatus and tl se upriglits are ln'eiierahlv reduced iu width adjacent the base as shown. The front ivall i0 of the oven is 'provided preferably 'with two door openin,als having closures ll; and other openiii. i3 are provided7 preterahlv in the 53S ot the orens and which bra-toni terminales short of the ivall l, lherehv forming a passage haring a coinniunication with the oven and the openings 235. 3G; so that heated air 'from the burner QG in the base iuar flor. through the openings 19 in the partition i2 and into the passage between the walls A,l and from Where it loivs into the oven.

The oven provided 'with a supiiilcnieutal bottoni -l-G spaced above the botiran to forni a passage 4T for the heated air 1naving communication ivitli the pass-ie@ hee tween the iralls a'- aind #l5 and apertures sl55 are provided in the bottoni lil 1which lead into the oven. Arranged bet-Ween the walls l and so as to engr the u'alli` is a centrally disposed tubular niernhc one end of which rests upon the top ot' the hase and over theol-lening SG therein. This inhular4 ineinber forms a sinall flue and also divides the space hetiveen the Walls l and l5 into passages .x10-51, one -cn each side of the flue 49, and these passaggesy have coniiuunication respectivel;v with the] opeuincjs .B5-31j AA liolloiv partition is arranged in the oven prefere-lily centralljY thereof and to extend from the front to the rear ivalhwto divide the oven into two chambers, one on :each side of the partition, and the door openingsin the front wall 40 are-'arranged l so that one will afford access to each ofthe chambers; The space in the partition 52 is of a width substantially equal tothe Width.

of the flue 49: and with which space the upper end of theiiue' 49 has communication adjacent the b'a'ck of the oven. The partition extends from the top 42 to the bottom ,38 and the side walls of the partition-are provided with openings 53 adjacent the top 42 of the oven, By extending the partition 52 .to the bottom 38 the space inthe partition will be closed to direct Comunication with the heat passage-47 and will divide` V,said passage intotWo passages 'one beneath each chamber of the oven. The due 49 communicates with the. space in the hollow partition 52 and also with the rear central Y compartment of the base tray. shown in Fig.

4;- Which. lcompartment .in turn communi' cates through the opening lZ with :the outlet flue 18... Shelves'- 54 may be provided in the two chambers of the oven, and may be Supported in any suitable manner. These shelves are perforated to permit the circula' .tion of heated air through the two chambers,

ivill be understood.

In 'order -to control thepassage of the heated air through the flue-Q49 a damper 55 provided in the due preferably above the opening 36, vand the handle 56 thereof pro- 1 jects through the Wall 45, whereby the dam- 35 per maybe easily manipulated Similar dampers 56,- 57 are provided in the passages 50.-51 and thehandles 58- 59 thereof` project Athrough the sides 39 so that the dampers may be easily actuated.

In operation, the dampers 20-21 are first adjusted so as to direct the products of com bustion from the burner in a direction tov flow to any one vor more of the. stove openings, and if the oven is. not to be used the dempers 5d-57 are adjusted to close the passages50.-5l as Wellv as the damper -5'5 to sulating material for conserving the heat.

Vhen it is desired to use both chambers o f the oven the dampers 15a 16a are rstr'closed and thel dampers 56--57 are adjusted to- -open the passages 50-5l, and the damper 5 is also adjusted Ato open the flue 49. The heated air from. the burner 26will theufflovv fionrtlie base through the open-v ings 19in the' partition-l2 andvthen into the passages 50-51' through the vrespective openings 35437. FromA the passages 50e-51. it will {iowinto the passage 47 at the bottom of' the oven land onthe respective sides of the partition 52, 'in-to' the tvvo chambers through ythe openings 48'4 in the supplemental bottom 46, which open# ings are located preferably someV distance from the passages' 50-5l so as to cause the heaatedair to flow under the entire bottom of the oven. From the tvvo chambers the heated air passes out of the top thereof andv `into thevhollow partition through the openings 53 in the Walls thereof. Fromthe hollow partition it will How down the due 49 outjthro-ugh the opening l? and flue 18. By manipulating the dampers`56--5T one or vthe other ofthe two .chambers may be out off from its supply of heated air,l and'by further manipulating these dampers any desired amount of heated air may be supplied to the oven, as Will be understood. The? `dampers or closures 44 of the openings 43 in the top 42 may be adjusted to control'the temperature in the oven chambers. @penings 60 may beprovided in the Walls 2: of."

the base, which communicate with vthe' space 25 for supplying outside. air to. the burner 26.. Racks 61 may be provided adjacent the Wall 45 for receiving dishes v62A to be War-med.
